UNITEDST'ITES sannon Gnzsn, oF-'s'i'iiv FRANCISCO,-csnrronlviaf\ i srnin'e l Application filed November I7-, 1921*.` 1 Serial A I radially disposed. Details of the structure will be described hereinafter, vin connectionV lwith the drawing. Y

In the accompanying one sheet of draw- Y ing I have illustrated a wheel containing my invention. Y' Y Figure 1 is a faceview of the wheel, partly broken awayv to show a portien'of the interior arrangement thereof.

Figure 2 is a cross-section on the yline 2, 2, u

of Figure 1.

Figure 3 is a fragmentary circumferential section taken at the line 3, 3, of Figure 2.

In the iguresz-The axle. is'repre'sented in conventional form at 1, and the hub there-` on at 2. These members may be secured'together by nut and washer 3, or in other manner.y At each end of hub 2 is a circum- Vfeiential flange l-"and 5, either of which may be integral with the hub, and either ofv which maybe a part of a sleeve, secured to the hub; Sleeve 6 is such a sleeve having the flange 5 formed as an integral Apart of it. The flanges d and 5 thus form chaiing plates for discs 7 and 8, which are parallel to each other, and extend circumferentially a distance depending on the diameter of the wheel. .y

Between the fchaing plates 4C and 5, on the hub 2, are two circumferential flanges, or a ring of sockets, 9, to receive the inner ends of the spokes 10, which may be secured therein byfbolts 11. The outer ends of the spokes engage in a rim 12, fitted between the discs 7 and 8, and capable of slight sliding motion therebetween. The rim 12 is mortised to receive the spokes, and has a row of sockets around its outer circumfer- Vence, in each of which is seated a coil spring A second rim-ring 14 surrounds the rim struction broadly.

18k are slightly less in diameter than the socketsl and 16, butare wedged therein by the end coils which are larger than the {body coils and fitv tightly into the sockets. Thus -the rcoils areiirmly positioned, 'but p free to move intheir action.

The discs7 and 8, may bek securedy to the outer riin 111, by 'bolts 17, andproject slight ly beyondl the rim'lfl'tov form a groove. for the reception of a rubber, or other,r tire 18. The discs 7 and 8, are cut out at the center as at`19 Figure 2,*butw-ithinY the circum.- p Vference ofthe chafing plates,toY permit theirv free radial movement.

The operation of the wheel, as above con- Y structed, is -as follows.l AThe wheelmay be either a driven wheel .or a driving wheel,

or-simplyl a rolling Wheel. lThe operation lwill be the vsame. rIhe weight of the vehicle and its load will be supported by the springs at approximately the lower side of the wheel, and those springs Awill be compressedfand those. dianietrically opposite them will eX- pandA to correspond, whilst the springs lateral of theuppe'r and lower ones will yield laterally the required degree, but will be held rmly in place by the end coilsr wedged tightly into the sockets. Thesame action will take place as the wheel passes over in-.

equalities in the roadway.

Inthe above action the side'discs,l7 and 8, slide radially between the chating plates, and with the tire and outer rim.

- I am aware that various kinds of springs have been positioned ybetween twoc'oncentric rims, therefore, Il do vnot claim `such con? Having thus described my invention, and an embodiment of it, inthe full, clear and exact terms required byj law, andV knowing that it comprises'novel, useful and valuable improvements in the art to which it pei' tains, I herey state that Ijdo not wish to be limited to the` precise construction and arrangement of the severalparts, as herein' set forth, as vvthe saine may be variously.
